ON Semiconductor NCP301LSN26T1G Voltage Detector

The ON Semiconductor NCP301LSN26T1G is a high-performance voltage detector designed for the precise monitoring of power supply voltages. This compact device is an essential component for a wide range of applications, including portable electronics, microprocessors, microcontrollers, and battery-powered devices where maintaining the correct operating voltage is crucial for system reliability and performance.

The NCP301LSN26T1G operates by monitoring the voltage level of its input and providing a reset signal output whenever the monitored voltage falls below a factory-programmed threshold. For the NCP301LSN26T1G, this threshold is set to 2.6V, making it well-suited for 3V and 3.3V systems. When the input voltage drops below this threshold, the device asserts a reset signal, which remains active until the input voltage recovers above the threshold, plus a built-in hysteresis margin, ensuring stable operation without false triggering.

One of the key features of this voltage detector is its low supply current, which is particularly beneficial for battery-powered applications where power conservation is a priority. The device's low current consumption helps extend battery life, contributing to the overall efficiency of the system it is protecting.

The NCP301LSN26T1G comes in a space-saving 5-pin TSOP package, making it ideal for use in space-constrained applications. Its compact size does not compromise its performance, as it offers a wide operating temperature range from -40°C to +125°C, allowing it to function reliably in harsh environmental conditions.

Additional features of the NCP301LSN26T1G include a built-in glitch immunity, which helps to prevent false resets due to short duration transients on the monitored voltage. This ensures that the device provides a stable and reliable reset output, which is critical for maintaining system integrity.

In summary, the NCP301LSN26T1G from ON Semiconductor is a robust and reliable solution for voltage monitoring and reset functions in electronic systems. Its precision, low power consumption, and compact form factor make it an excellent choice for designers looking to enhance their system's safety and efficiency.
